Abstract
The notorious overhead occurs at the medium access control (MAC) layer prevents the Wireless LANs (WLANs) from achieving desirable performance. This problem becomes even severe in the upcoming very high-speed WLANs, in which the physical layer (PHY) rate may exceed 216Mbps. To alleviate overhead, we propose a new MAC layer scheme --- Aggregation with Fragment Retransmission (AFR). In this scheme, multiple packets rather than one are aggregated into and transmitted in a single large frame. If some are lost during the transmission, only the corrupted parts of the large frame will be retransmitted. This aggregation with partial retransmission technique allows for more efficient use of the wireless medium, since one frame transmission is expected to cause much less overhead than multiple packets transmissions do if properly designed. A theoretical analysis is used to evaluate AFR's performance. Extensive
